On the size of $h$ -fold sumsets

Shi-Qiang Chen, Quan-Hui Yang

Let $h$ be a positive integer, and let $A$ be a finite set of integers. We derive an exact formula for $∣ h A ∣$ . Furthermore, let $A = {0, 1, \dots, s, a, b}$ , $1 \leq s < a < b$ , and write $…

On the Monotonicity of Higher-Fold Representation Functions

Csaba SÃ¡ndor, Quan-Hui Yang

For a positive integer $h$ , let $R_{A, h} (n)$ denote the number of ordered representations $n = s_{1} + \dots + s_{h}$ with all $s_{i} \in A$ . Let \[ B=\{0\}\cup\{m\ge 1:\text{ the base-4 expan…
